R Literate Programming Document
This is my attempt to create a document out of the inclass coding scripts.
Step 1 : Load tidyverse library and data

## ✖ dplyr::filter() masks stats::filter()

Step 3: check whether it is a data frame or a tibble?
If it is a data frame we will get an output as True. In case it is a tibble then the output will be False, so we need to convert it into tibble by using as_tibble
is.data.frame(indata)## [1] TRUEindata <- as_tibble(indata)
is_tibble(indata)## [1] TRUEStep 4 : Need to check the summary of data

## # … with 17 more rowsStep 12 : Within the countries, we need to fill missing values by using downup()
indata_filled <- indata_pivoted %>% group_by(Country.Name) %>% fill(Fertility.Rates, .direction = "downup") %>% ungroup()Step 13 : We have to check whether the missing values are completely removed or not.
indata_filled %>% filter(is.na(Fertility.Rates)) %>% group_by(Country.Name) %>% summarise(count = n())## # A tibble: 9 × 2
## Country.Name count
## <fct> <int>
## 1 American Samoa 52
## 2 Cayman Islands 52
## 3 Faeroe Islands 52
## 4 Monaco 52
## 5 Northern Mariana Islands 52
## 6 San Marino 52
## 7 Sub-Saharan Africa (IFC classification) 52
## 8 Turks and Caicos Islands 52
## 9 Tuvalu 52Step 14 : Filter all countries with missing values and removing them
indata_filled <- indata_filled %>% filter(!is.na(Fertility.Rates))Step 15 : Plot a scatter plot, where x-axis = Year and Y axis = Fertility.Rates
ggplot(data = indata_filled) + geom_point(mapping = aes(x=Year, y = Fertility.Rates))
Step 16 : Plot a scatter plot with a smoothing line
ggplot(data = indata_filled) + geom_point(mapping = aes(x=Year, y = Fertility.Rates), position = "jitter", alpha = 0.1) + geom_smooth(mapping = aes(x=Year, y = Fertility.Rates)) + labs(x = "Year", y = "Fertility Rates", title = "Fertility Rates over the years", subtitle = "Global fertility rates have decreased since 1960")## `geom_smooth()` using method = 'gam' and formula = 'y ~ s(x, bs = "cs")'
Step 17 : Need to categorize 210 countries by two ways option1 : So many data points are there, we need to reduce some of them so we are subsetting the data.
indata_subset <- filter(indata_filled, Country.Name %in% c("United States", "Mexico", "Canada"))
ggplot(data = indata_subset) + geom_line(mapping = aes(x=Year, y = Fertility.Rates, color = Country.Name), alpha = 0.5) + labs(x = "Year", y = "Fertility Rates", title = "Fertility Rates over the years", subtitle = "Global fertility rates have decreased since 1960")
Option 2 : 210 countries categorize by selecting based on statistics and printing 10 countries by using top_n(10)
indata_filled %>% group_by(Country.Name) %>% summarise(avg = mean(Fertility.Rates)) %>% arrange(desc(avg)) %>% print(n = 10)## # A tibble: 210 × 2
## Country.Name avg
## <fct> <dbl>
## 1 Niger 7.59
## 2 Afghanistan 7.47
## 3 Yemen, Rep. 7.43
## 4 Somalia 7.26
## 5 Rwanda 7.23
## 6 Burundi 7.19
## 7 Angola 7.06
## 8 Uganda 6.94
## 9 Mali 6.92
## 10 Chad 6.92
## # … with 200 more rowsPrint bottom 10 countries by using top_n(-10)
indata_filled %>% group_by(Country.Name) %>% summarise(avg = mean(Fertility.Rates)) %>% arrange(desc(avg)) %>% top_n(-10) %>% ggplot() + geom_bar(mapping = aes(x = Country.Name, y = avg), stat = "identity") +coord_flip()## Selecting by avg
Step 18 : If there is no countrycode library then need to install it.
library(countrycode)Step 19 : Need to do optioning Adding a new variable called continent and grouping them by country name
indata_df <- as.data.frame(indata_filled)
indata_df$Continent.Name <- factor(countrycode(sourcevar = indata_df[,"Country.Name"], origin = "country.name", destination = "continent"))## Warning in countrycode_convert(sourcevar = sourcevar, origin = origin, destination = dest, : Some values were not matched unambiguously: Channel Islands, Kosovo, Latin America & Caribbean (all income levels), OECD members, Other small states, Pacific island small statesStep 20 :Adding a new variable called region and grouping them by country
indata_df$Region.Name <- factor(countrycode(sourcevar = indata_df[,"Country.Name"], origin = "country.name", destination = "region"))## Warning in countrycode_convert(sourcevar = sourcevar, origin = origin, destination = dest, : Some values were not matched unambiguously: Latin America & Caribbean (all income levels), OECD members, Other small states, Pacific island small statesStep 21: Here, in the result we can observe countries divided by continent name and region name
head(indata_df)## Country.Name Year Fertility.Rates Continent.Name Region.Name
## 1 Aruba 1960 4.820 Americas Latin America & Caribbean
## 2 Aruba 1961 4.655 Americas Latin America & Caribbean
## 3 Aruba 1962 4.471 Americas Latin America & Caribbean
## 4 Aruba 1963 4.271 Americas Latin America & Caribbean
## 5 Aruba 1964 4.059 Americas Latin America & Caribbean
## 6 Aruba 1965 3.842 Americas Latin America & CaribbeanStep 22 : Convert data into tibble by using as_tibble
indata <- as_tibble(indata_df)
head(indata)## # A tibble: 6 × 5
## Country.Name Year Fertility.Rates Continent.Name Region.Name
## <fct> <int> <dbl> <fct> <fct>
## 1 Aruba 1960 4.82 Americas Latin America & Caribbean
## 2 Aruba 1961 4.66 Americas Latin America & Caribbean
## 3 Aruba 1962 4.47 Americas Latin America & Caribbean
## 4 Aruba 1963 4.27 Americas Latin America & Caribbean
## 5 Aruba 1964 4.06 Americas Latin America & Caribbean
## 6 Aruba 1965 3.84 Americas Latin America & CaribbeanStep 23: Plotting Fertility rates by differentiating by continent name
ggplot(data = indata) + geom_point(mapping = aes(x=Year, y = Fertility.Rates, color = Continent.Name), position = "jitter", alpha = 0.6) + labs(x = "Year", y = "Fertility Rates", title = "Fertility Rates over the years", subtitle = "Global fertility rates have decreased since 1960")
From the above graph we can see the fertility rates of different
continents
Step 24 : Plotting the counties in Middle East & North Africa region and Asian continent
indata %>% filter(Region.Name == "Middle East & North Africa" & Continent.Name == "Asia") %>% ggplot() + geom_line(mapping = aes(x =Year, y = Fertility.Rates, color = Country.Name), size = 1, linetype = 2)## Warning: Using `size` aesthetic for lines was deprecated in ggplot2 3.4.0.
## ℹ Please use `linewidth` instead.
Step 25 : Plot a Boxplot of different continent Fertility rates
ggplot(data = indata, mapping = aes(x = Continent.Name, y = Fertility.Rates)) + geom_boxplot() + coord_flip()
Step 26 : Plot a Histogram
ggplot(data = indata) + geom_histogram(mapping = aes(x = Fertility.Rates), binwidth = 0.5)
Step 27 : calculating average and plotting the average of different regions by using Bar graph
indata %>% group_by(Region.Name) %>% summarise(avg = mean(Fertility.Rates)) %>% ggplot(mapping = aes(x = reorder(Region.Name, -avg), y = avg, fill=Region.Name)) + geom_bar(stat = "identity") + coord_flip()
